You will not see the accuracy potential from these guns unless you reload. Very impressive, group Rangefinder, will you share your recipees? Both Cast and jacketed?
Thanks CZVZ

Nice shooting Rangefinder,I shoot the same cast bullet as you in my M44 but I use the Universal Load of 16.0 grs. Alliant 2400 mostly the Red Dot loads works just as well. I'm currently in the process of working up so jacketed bullet loads but haven't done any testing yet. My M44 bore is .312 groove to groove.
